Biopolymers & Bioplastics

Organic Polymers

Organic polymers are macromolecules composed of many repeating monomer units. Both synthetic and natural polymers play a crucial role in everyday life. Polysaccharides, polypeptides, and polynucleotides are the main types of biopolymers in living cells. These polymers are synthesized by enzyme-mediated processes in cells. In general, synthetic polymers are derived from monomers that contain either a multiple bond, or two or more functional groups, or a three-to seven- membered ring.. The chemical properties of the polymers are derived from their monomer units, while the physical properties of polymers are different. Polymers, depending on their physical properties, are characterised as thermoplastics, thermo sets, elastomers and fibres.Organic polymers have wide variety of uses, for example: polystyrene resins are used in the production of home electronics and appliances; nylon-6 is used in textile and plastic industries. Organic polymers such as polyethylene terephthalate are in the manufacture of popular PET bottles. Others such as neoprene are used in shoe soles and wet suits, polyvinyl chloride in pipes and Teflon in non-stick pans.
